Description

Technical Field

[0001] This invention belongs to the field of atomizer technology, and specifically relates to a built-in electromagnetic induction heating atomizing core and an atomizer using the atomizing core. Background Technology

[0002] Currently used inhalation aerosol generators are generally devices that use electric heating to atomize a special liquid. They can be used in fields such as inhalation therapy, but the most commonly used type is the inhalation aerosol generator commonly known as "electronic cigarettes." It includes an atomizer, inside which is a heated atomizing component called the atomizing coil, and most atomizing coils are heated by resistance wire.

[0003] A search revealed that Chinese patent application CN201921134547.5, filed on July 19, 2019, discloses a built-in electromagnetic induction heating atomizing core and an atomizer using the same core. The core includes an atomizing core shell, an oil guiding component, a heating component, and an alternating magnetic field assembly. The atomizing core has a vapor outlet at the upper end, an air inlet at the lower end, and an e-liquid inlet on the middle side wall. The oil guiding component, heating component, and alternating magnetic field assembly are arranged sequentially from the outside to the inside inside the atomizing core shell. The oil guiding component is axially and tightly attached to the inner wall of the atomizing core shell; the heating component is axially and tightly attached to the inner wall of the oil guiding component; the alternating magnetic field assembly is axially positioned inside the heating component, and an axial annular air passage is provided between the assembly and the heating component. A locking platform is provided at the upper end of the atomizing core shell, and a bottom cover is provided at the lower part of the shell. This structure ensures the fixed distance and coaxiality of the electromagnetic coil, magnetic core, and heating element, guaranteeing a stable and reliable electromagnetic induction effect. This also avoids the uneven distribution of e-liquid caused by oil entering from one end.

[0004] However, this device still has the following drawbacks: Although it can ensure the fixed distance and coaxiality of the electromagnetic coil, magnetic core, and heating element, guaranteeing a stable and reliable electromagnetic induction effect, and avoid the uneven distribution of e-liquid caused by one-end oil inlet, the heating method, which involves supplying e-liquid evenly through an e-liquid inlet located on the atomizer core shell, is inefficient and cannot continuously provide the atomizer with the necessary conditions for atomization, resulting in a less than ideal dispersion effect after atomization.

[0015] The beneficial effects of this invention are:

[0016] 1. The liquid storage shell is used to collect liquid. While the water pump is working continuously, the liquid in the storage shell is pumped through the water pump. Under the action of the diversion component, the liquid is evenly distributed in different positions in the atomizing component, creating an atomizing environment around the atomizing component.

A straight threaded cylinder is used to thread and fit onto the outer wall of the electromagnetic induction heater, allowing the electromagnetic induction heater to be quickly assembled onto the inner wall of the first mounting hole. When the electromagnetic induction heater needs maintenance, simply use a tool to rotate the electric heating coil to separate the electromagnetic induction heater from the straight threaded cylinder, thus improving the efficiency of replacing the electromagnetic induction heater.

[0018] 3. By opening the second one-way valve, the liquid in the second assembly hole enters the heat pipe through the water inlet pipe. The liquid level sensor constantly monitors the liquid position in the heat pipe and the bend joint. Based on the signal from the liquid level sensor, the water pump determines whether to continuously inject liquid into the heat pipe. As the heat pipe extends into the electric heating coil, the liquid in the heat pipe is rapidly heated, thus improving the efficiency of liquid heating.

[0019] 4. By opening the first one-way valve and the micro fan, the atomized gas generated after heating in the heat pipe enters the housing, and the gas generated by the micro air pump is introduced into the guide pipe through the first through hole, so that the atomized gas in the housing is dispersed outward and discharged outward through several sets of first assembly holes, thereby improving the flow efficiency of the atomized gas.

A liquid storage shell 4 is fixedly connected to one outer wall of the assembly base 1. A water pump 5 is fixedly connected to the end of the liquid storage shell 4 on the side away from the motor 2.

A water filling cap 8 is threadedly connected to the top of the liquid storage shell 4 on the side away from the water pump 5.

[0033] Specifically, the liquid storage shell 4 is used to collect liquid. While the water pump 5 is working continuously, the liquid in the liquid storage shell 4 is pumped by the water pump 5, so that the liquid is evenly distributed in different positions in the atomizing component 7 under the action of the diversion component 6, so that an atomizing environment is generated around the atomizing component 7. While the motor 2 is continuously driving the atomizing component 7 to rotate, the atomizing component 7 is evenly dispersed.

[0034] The diversion assembly 6 includes a bearing 61; for example, such as Figure 2 As shown.

[0035] The bearing 61 is rotatably connected to a metal tube 62, and the top of the metal tube 62 is connected to the output end of the water pump 5. The bearing 61 is embedded in the top of the atomizing component 7, and the central axis of the atomizing component 7 coincides with the central axis of the bearing 61. The bottom of the metal tube 62 is fixed and connected to a linkage tube 63, and the linkage tube 63 extends into the interior of the atomizing component 7. The outer wall of the linkage tube 63 is fixed and connected to several sets of water injection hoses 64.

[0036] The atomizing component 7 includes an assembly sphere 71 and an energy storage mechanism 75; for example, such as Figure 3 As shown.

[0037] The surface of the assembly sphere 71 is provided with a plurality of first assembly holes 72, and the plurality of first assembly holes 72 are distributed at different positions on the assembly sphere 71. The inner wall of the plurality of first assembly holes 72 and the side near the port is provided with a second assembly hole 73. The second assembly hole 73 is interconnected with the first assembly hole 72, and the inner wall of the second assembly hole 73 is fixedly connected to the outer wall of the water injection hose 64. A micro air injection pump 74 is fixedly connected to the inner wall of the plurality of first assembly holes 72 and the side away from the second assembly hole 73. The energy storage mechanism 75 is fixedly connected to the inner wall of the first assembly hole 72, and the energy storage mechanism 75 is interconnected with the micro air injection pump 74 and the second assembly hole 73.

[0038] The energy storage mechanism 75 includes a limiting part 751, a first flow guide part 754, and a second flow guide part 755; for example, as shown... Figure 4 As shown.

[0039] The limiting part 751 is fixedly connected to the inner wall of the first mounting hole 72, and an electromagnetic induction heater 752 is threadedly connected to the limiting part 751. An electric heating coil 753 is provided on the outer wall of the electromagnetic induction heater 752 on the side away from the micro air pump 74. The first flow guide 754 is located at one end of the electric heating coil 753, and the first flow guide 754 is in communication with the limiting part 751. The second flow guide 755 extends to the inner wall of the electric heating coil 753, and the second flow guide 755 is in communication with the first flow guide 754 and the second mounting hole 73.

[0040] Specifically, the electromagnetic induction heater 752 is threadedly connected to the limiting part 751, making it easy to assemble the electromagnetic induction heater 752 into each set of first mounting holes 72. After the first guide part 754 and the second guide part 755 are fixedly connected, the second guide part 755 is extended into the interior of the electric heating coil 753, so that the limiting part 751, the first guide part 754, the second guide part 755 and the second mounting hole 73 are in a connected state. When the liquid in the second mounting hole 73 enters the second guide part 755, the electric heating coil 753 rapidly heats the liquid in the second guide part 755, and the atomized gas generated after heating enters the first guide part 754. Under the continuous operation of the micro air pump 74, the gas is injected into the limiting part 751 and the first guide part 754, so that the atomized gas is evenly sprayed out from the first mounting hole 72.

[0041] The limiting part 751 includes a straight threaded cylinder 7511; for example, such as Figure 5 As shown.

[0042] A limiting ring 7512 is fixedly connected to the outer wall of the straight threaded cylinder 7511. The limiting ring 7512 is fixedly connected to the inner wall of the first assembly hole 72 and to the side away from the micro air pump 74. The surface of the limiting ring 7512 is provided with a plurality of first through holes 7513. The plurality of first through holes 7513 are arranged in a ring array with the central axis of the limiting ring 7512 as the center, and the plurality of first through holes 7513 are all connected to the output end of the micro air pump 74.

[0043] The first guide portion 754 includes a housing 7541; for example, such as Figure 6 As shown.

[0044] The outer wall of one side of the housing 7541 has several sets of second through holes 7542, which are arranged in a ring array around the central axis of the housing 7541. The housing 7541 and the limiting ring 7512 have the same dimensions. The outer wall of the other side of the housing 7541 is fixed and connected to several sets of guide pipes 7543, which are arranged in a ring around the central axis of the housing 7541. The flow guide tubes 7543 and the second through hole 7542 are arranged in a circular array, and the ends of several sets of flow guide tubes 7543 are movably snapped to the inner wall of the first through hole 7513. The top of the inner wall of the housing 7541 is fixedly connected to a flow drain tube 7544. A micro fan 7545 and a first one-way valve 7546 are provided on the flow drain tube 7544, and the first one-way valve 7546 is located near the bottom end of the flow drain tube 7544.

[0045] The second flow guide 755 includes a heat pipe 7551; for example, such as Figure 7 As shown.

[0046] One end of the heat pipe 7551 is fixedly connected to a sealing block 7552, and the other end of the heat pipe 7551 is fixedly connected to a bend connector 7553. A liquid level sensor 7557 is installed on the bend connector 7553. A third through hole 7554 is formed at the top of the heat pipe 7551, near the bend connector 7553. The third through hole 7554 is fixedly connected to and communicates with the end of the drain pipe 7544. A heat insulation baffle 7555 is fixedly connected to the outer wall of the device, and the heat insulation baffle 7555 is located on the side near the third through hole 7554. One end of the bent pipe joint 7553 is fixed and connected to a water inlet pipe 7556, and a second one-way valve 7558 is provided on the water inlet pipe 7556. The liquid level sensor 7557 is located on the side near the bent pipe joint 7553. The end of the water inlet pipe 7556 is fixedly connected to the inner wall of the second assembly hole 73 and communicates with it.

[0047] Specifically, the straight threaded cylinder 7511 is used to thread onto the outer wall of the electromagnetic induction heater 752, so that the electromagnetic induction heater 752 can be quickly assembled into the inner wall of the first assembly hole 72. When the electromagnetic induction heater 752 needs to be repaired, the electric heating coil 753 can be rotated with a tool to separate the electromagnetic induction heater 752 from the straight threaded cylinder 7511, thereby improving the efficiency of replacing the electromagnetic induction heater 752.

[0048] The opening of the second one-way valve 7558 allows the liquid in the second assembly hole 73 to enter the heat pipe 7551 through the water inlet pipe 7556. The liquid level sensor 7557 continuously detects the position of the liquid in the heat pipe 7551 and the elbow joint 7553. Based on the signal fed back by the liquid level sensor 7557, the water pump 5 determines whether to continuously inject liquid into the heat pipe 7551. As the heat pipe 7551 extends into the electric heating coil 753, the liquid in the heat pipe 7551 is rapidly heated.

[0049] The opening of the first one-way valve 7546 and the micro fan 7545 allows the atomized gas generated after heating in the heat pipe 7551 to enter the housing 7541. The gas generated by the micro air pump 74 is introduced into the guide pipe 7543 through the first through hole 7513, causing the atomized gas in the housing 7541 to be released outwards and discharged outwards through several sets of first assembly holes 72.

[0050] The working principle of the built-in electromagnetic induction heating atomizing core and the atomizer using the atomizing core proposed in the embodiments of the present invention is as follows:

[0051] The straight threaded cylinder 7511 is threaded onto the outer wall of the electromagnetic induction heater 752, allowing the electromagnetic induction heater 752 to be quickly assembled onto the inner wall of the first mounting hole 72. When the electromagnetic induction heater 752 needs maintenance, simply use a tool to rotate the electric heating coil 753 to separate the electromagnetic induction heater 752 from the straight threaded cylinder 7511, thereby improving the efficiency of replacing the electromagnetic induction heater 752.

[0052] By opening the second one-way valve 7558, the liquid in the second assembly hole 73 enters the heat pipe 7551 through the water inlet pipe 7556. The liquid level sensor 7557 continuously detects the liquid position in the heat pipe 7551 and the elbow joint 7553. Based on the signal fed back by the liquid level sensor 7557, the water pump 5 determines whether to continuously inject liquid into the heat pipe 7551. As the heat pipe 7551 extends into the electric heating coil 753, the liquid in the heat pipe 7551 is rapidly heated.

[0053] By opening the first one-way valve 7546 and the micro fan 7545, the atomized gas generated after heating in the heat pipe 7551 enters the housing 7541, and the gas generated by the micro air pump 74 is introduced into the guide pipe 7543 through the first through hole 7513, so that the atomized gas in the housing 7541 is dispersed outward, and the atomized gas is discharged outward through several sets of first assembly holes 72.

[0054] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
